+The above will use these style guidelines on all of your Perl sources. More advanced users might want to configure other styles for different projects and check buffer-file-name to switch styles on a per-buffer basis. You might also want to look into setting many of the cperl-electric-* variables or cperl-hairy. They add a lot of neat features for automatic code completion in Perl.
